Different settings for emacs -nw

Question

I was wondering what to put in my .emacs file to have different settings depending on whether I run a normal emacs session or whether I run emacs in the terminal with emacs -nw?

Answer 1

You can use the variable window-system-version to tell if you are on a terminal. If this variable is nil, then it is terminal mode.

Example .emacs:

(when window-system-version
  ;; setup for graphic environment
)
